SANITARY MOUTHPIECE FOR TELEPHONES.

Application filed September 17, 1923. Serial No. 683,154.

This invention relates to improvements in mouth pieces for telephones, and more especially to a sanitary construction f mouth piece which will be interchangeable with the usual telephone mouth piece.

An object of the invention is to provide a suitable sanitary mouth piece for telephones, which will be so constructed that the breath or saliva tron the mouth of the person telephoning will not enter into the said mouth piece.

Another object of the invention is to provide a. sanitary mouth piece for telephones which will be so constructed that it will not only be interchangeable with the usual type of mouth piece, but will also he so arranged that the breath from the person telephoning will pass on an angle down under the mouth piece instead of into the same.

A further object of the invention is to provide a sanitary mouth piece for tele phones which will be highly eiiicient in use and quite inexpensive to manufacture.

Other objects will appear as the description proceeds.

In the accompanying drawings which constitute a part of my application Figure l is a side elevation of a portion of a telephone equipped with an improved form of sanitary mouth piece, which constitutes our invention, and

Figure 2 is a front elevation ot the mouth piece.

Like characters of reference are used throughout the specification and accompanying drawings to designate corresponding parts.

The telephone transmitter 1 is formed in the usual manner and is adapted to receive the threaded end 2 of our improved sanitary mouth piece The mouth piece 3 is made much like the usual form of mouth piece, except that it extends out farther at the upper outer end than it does at the lower end, and is provided with an inwardly or downwardly slanting perforated wall 4:. As clearly illustrated in the drawings, the perforations 5 extend-on an upward incline through the wall t, in such a manner to prevent the breath of the person telephoning from entering the interior of the mouth piece, while the voice will have a ready access to the transn'iitter.

The operation of the sanitary mouth piece will be as follows: lVhen a person is talking into the transmitter, the v ice will have an unrestricted passage direct to the transmitter, but the breath or possible salivai'rom the persons mouth will first hitthe wall of the mouth piece and will be directed down the slanting surface, instead of passing into the interior of the said mouth piece, Thus, it will be seen that we have invented and produced a mouth piece for telephones which will be of a highly sanitary nature, and which will be quite inexpensive to manufacture.

Many minor changes in detail of description may be resorted to without departure from the spirit of the invention.

Having thus described our invent-ion what we claim as new and desire to secure by Letters Patent of the United States 1. A sanitary mouthpiece tor telephones con'iprising a body portion screw threaded at its inner end, the outer end thereof being provided with a perforated wall, the openings through said wall extending upwardly and in parallel relation one with the other.

2. A sanitary mouthpiece for telephones comprising a body portion screw threaded at its inner end, the outer end thereof being novided with a slanting perforated wall, all of said openings extending upwardly in spaced parallel relation, one with the other.

In testimony whereof we aliix our signatures.
